9mm Unique with Small piston MAGNUM?


Recommended Posts

First, did he start at the manual's starting load?

What bullet weight is he using?

Usually, if one has an established load, one would reduce the charge weight by 2% and work up when switching to magnum primers.

5.6gr can easily be an over-MAX load for 115r and heavier bullets.

I start at 4.5gr for Unique and 115gr bullets and work up.
